Application May 11, 1932. Serial No. 610,678

2 Claims.

This invention has reference to battery terminal connections, the primary object of the invention being to provide a connection which may be readily and easily removed or replaced without the use of a wrench, and one wherein a secure connection between the cable and battery terminal will be maintained at all times.

An important object of the invention is the provision of a device of this character which may be positioned without the danger of breaking or distorting the battery post, to render the battery inoperative.

Another important object of the invention is to provide a connection wherein the removable battery post engaging member swings inwardly in a true horizontal plane, thereby preventing damage to the battery post, which usually results in the use of connectors wherein a securing wedge is used, the securing wedge having direct contact with the battery post.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the inven tion.

Referring to the drawing:

Figure 1 is a longitudinal sectional view through a battery terminal connection, constructr ed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the battery terminal connection, taken at right angles to Figure 1 and illustrating the connection as positioned on a battery post.

Referring to the drawing in detail, the connection comprises a body portion indicated generally by the reference character 5, the same being constructed of suitable conducting material commonly used in the construction of battery terminal connections.

The body portion is formed with a tapered opening for the reception of the battery post, the battery post being indicated by the reference character 6,

As shown, the opening is of a diameter slightly greater than the diameter of the battery post 6, so that the body portion will fit loosely on the battery post.

A cut away portion indicated at '7, is formed within the body portion 5, and communicates with the opening of the body portion in which the battery post 6 is positioned, in use.

Pivotally mounted at one of its ends, and disposed within the cut out portion '7, is a curved arm 8, which is formed with teeth 9 disposed along its inner curved surface, which teeth are designed to bite into the battery post, in a manner as shown by Figure 1 of the drawing.

The length of the arm 8 is such that it extends beyond one edge of the body portion, providing a shoulder 9, which may be struck by any suitable tool, to disengage the arm and battery post.

Mounted within the cut out portion 7, is a Wedge 10, which is of a length so that the ends thereof extend appreciable distances beyond the sides of the body portion, where the wedge may be struck by a tool to securely position or remove the wedge.

In order that the wedge 10 will be held within the body portion 5 at all times, a cotter key 11 is provided, which cotter key extends through the narrow end of the wedge.

The reference character 12 designates the cable which is in circuit with the battery post, through 8 the body portion 5.

In the use of the device, the wedge 10 is moved to a position so that the arm 8 may swing rearwardly. With the arm 8 in this position, the body portion 5 is positioned over the battery post. The wedge 10 is now driven by striking the large end thereof with a hammer or other suitable tool resulting in the arm 8 being moved into close engagement with the battery post, the teeth thereof biting into the battery post.

Due to this construction, a close fit is insured between the battery terminal connection and the battery terminal.

Should it be desired to remove the battery terminal connection, the small end of the wedge 10 is struck with a tool driving the wedge to its inactive position.

By tapping the shoulder 9, the arm 8 will be moved to disengage the battery terminal or post 6, whereupon the connection may be readily re:. moved.

Having thus described the invention what is claimed is:

We claim:

1. In a battery terminal connection, the com bination of a body portion having an opening to accommodate a battery post and having a lateral opening communicating with the battery post opening, an arm pivotally mounted within the last mentioned opening of the body portion and adapt-.

ed to swing to a position to engage the battery post, one end of the arm extending beyond the body portion, providing a shoulder to be struck by a tool to disengage the arm and battery post, and a wedge shaped member positioned Within 5 the body portion, and engaging one edge of the arm, moving the arm to its active position.

2. In a battery terminal connection, the combination of a body portion having an opening to accommodate a battery post, said body portion 10 having a cut out portion extending to the open ing, a curved arm pivotally supported within the cut out portion and having one of its ends extended beyond the side of the body portion, a wedge extended within the cut out portion and engaging one edge of the cut out portion and the curved arm, moving the curved arm into engagement with the battery post with which the body portion is used, and one end of the curved arm presenting a shoulder to be struck by a tool, moving the curved arm out of engagement with the battery post;
